CVE-2022-37032

Published: 19 September 2022

An out-of-bounds read in the BGP daemon of FRRouting FRR before 8.4 may lead to a segmentation fault and denial of service. This occurs in bgp_capability_msg_parse in bgpd/bgp_packet.c.

Notes

AuthorNote
mdeslaur
code is similar in quagga, probably vulnerable
the frr patch for this issue is incompatible with quagga, as
is requires the size of the struct to be changed:
https://github.com/FRRouting/frr/commit/a46a2e9b4e8de782ac07e01429a80ed7ec167dcb
changing the size of that struct causes s390x to fail tests.
